ABSTRACT:
A liquid crystal display device containing a fluorescent material comprises a pair of electrodes, a pair of substrates, and an element for making liquid crystal mixtures in such a molecular orientation that the fluorescent materials generate no fluorescence at a selected portion of the pair of electrodes and accordingly no fluorescence penetrates through the liquid crystal mixtures. The element comprises a liquid crystal molecule orientation layer made of a layer of surfactant or electric power sources. The liquid crystal molecule orientation is formed over the pair of electrodes to produce a homeotropic orientation of a nematic mesophase. The electric power sources are applied to the pair of electrodes to form the homeotropic orientation of the nematic mesophase in a background area of the display device opposed to a display area of it.
